Thin Ice: Global Warming May Be Raising Drowning RisksWEDNESDAY, Nov. 18, 2020 (HealthDay News) -- More children and young adults are drowning in winter lakes because of warming temperatures that create unstable lake ice, a new study finds.A team of international researchers examined several decades of data, including 4,000 drownings and population information from throughout Canada, 14 U.S. states, Estonia, Germany, Latvia, Finland, Russia, Sweden and regions of Italy and Japan.

Exoskeleton Helps Paralyzed People Walk AgainWEDNESDAY, Nov. 18, 2020 (HealthDay News) -- People paralyzed with spinal cord injuries can safely and effectively use an exoskeleton to assist them in walking, a new study finds."Participants showed improvement regardless of level of injury, completeness or duration of injury," said Gail Forrest, director of the Tim and Caroline Reynolds Center for Spinal Stimulation at Kessler Foundation in East Hanover, N.J.The findings suggest "that exoskeletons can be used to improve mobility across a broad spectrum of individuals with neurological deficits caused by spinal cord injury," she said in a foundation news release.The randomized clinical trial included 50 participants with paralysis either in the lower body or in both the upper and lower body. This included people with no motor...

Overweight With Arthritic Knees? You Might Want to Avoid TennisTUESDAY, Nov. 17, 2020 (HealthDay News) -- Stay off the court: For overweight people with arthritic knees, racket sports like tennis and racquetball may accelerate degeneration of the joints, a new study finds.Exercise can benefit overweight people, but the wrong type might damage knees and lead to the need for knee replacement surgery, the researchers said."Fast-paced and high shear load physical activities, such as racket sports, are more harmful for overall knee joint health," said lead researcher Dr. Silvia Schiro, from the University of California, San Francisco.Racket sports include frequent and high-intensity lateral movements that can worsen knee osteoarthritis, as opposed to activities that mostly involve forward movements -- such as running, an elliptical machine, swimming...

Amid Lockdowns, Online Exercise Classes Help Seniors Feel Less AloneTUESDAY, Nov. 17, 2020 (HealthDay News) -- Participating in group exercise classes is good for seniors and not just in the ways one might expect.The classes reduce loneliness and social isolation, according to a new study. And early results suggest that's true even after the coronavirus pandemic forced those classes to meet virtually."As the demographics of our country shift, more people are living alone than ever before," said study co-author Dr. Allison Moser Mays, a geriatrician at Cedars-Sinai Medical Center in Los Angeles."The number of adults over the age of 65 in the U.S. is expected to reach more than 70 million by 2030 -- double what it is now. We need sustainable ways to help this burgeoning population thrive as they age, or there will be widespread consequences," Mays said...
